Added in 2.6.28, but from then all Agere cards will execute 
orinoco_dl_firmware and clear 1K of stack, regardless of whether there 
is firmware in /lib/firmware. I'm not certain it'll blow the stack, but 
the remaining download functions don't use much more so it'll be close.

Basically, I expect anyone configuring 4k stacks and using an Agere card 
to see the problem you saw. Which is a regression wrt 2.6.27.
